os.access(file, os.R_OK) on UNIX and WINDOWS

[kai rosenthal]

Hello,

on UNIX I changed the permission of a file "myfile" with chmod 000
myfile. Then I got 0 from os.access(myfile, os.R_OK). This is ok.

Then I checked the same file on WINDOWS (with samba):
I got "True" from os.access(myfile, os.R_OK). I think it is not ok?!

In my python script I check the return value of os.access(myfile,
os.R_OK) and when it is "True" I copy the file with shutil.copy(myfile,
newfile).
But on WINDOWS I get the error: IOError: [Errno 13] Permission denied.

How can I check the right file access with python on WINDOWS before
copying the file?
Is it a samba configuration?

Thank' for your hints, Kai

Windows: get owner and group of a file

[kai rosenthal]

Hello,

with ls -l on windows I get
-rw-r--r-- 1 500 everyone 320 Nov 09 09:35 myfile

How can I get on windows with a standard python 2.2 (without windows
extensions) the information "500" and "everyone" (owner and group)?
Also I cannot use popen('ls -l').

With
import stat
stat_info = os.lstat(myfile)
owner = "%-8s" % stat_info.st_uid
group = "%-8s" % stat_info.st_gid
I get 0 for owner and group.

Thanks for your hints, Kai

com: makepy gencache.EnsureModule

[Kai Rosenthal]

Hello,

I' having a problem with gencache.EnsureModule:

I used win32com\client\makepy.py to successfully generate Python
sources.
Unfortunately, after I call win32com.client.Dispatch(), the object I
get back is of type "COMObject" instead of one of the generated
classes.

In particular, I'm trying to interact with SolidWorks Extensibility
Type Library and the PROGID is "SldWorks.Application".

Using win32com\client\makepy.py -i
SolidWorks Extensibility Type Library
 {801A-A66C-11D3-A8BD-861EBBD6}, lcid=0, major=1, minor=0
 >>> # Use these commands in Python code to auto generate .py support
 >>> from win32com.client import gencache
 >>> gencache.EnsureModule('{801A-A66C-11D3-A8BD-861EBBD6}',
0, 1, 0)

Looking in win32com\gen-py, the appropriate file _does_ exist:
801A-A66C-11D3-A8BD-861EBBD6x0x1x0.py
and it does contain the correct class definitions.

Then, in my code:
>>> mod = 
>>> win32com.client.gencache.EnsureModule('{801A2001-A66C-11D3-A8BD-861EBBD6}',
>>>  0, 1, 0)
>>> mod
None
>>> ob = win32com.client.Dispatch("SldWorks.Application")
>>> ob


Why are the object mod is None and the object ob is   instead  >?
Any bright ideas as to what's going wrong here?

Thanks for your hints, Kai

resolve environment variables in string - regular expression

[Kai Rosenthal]

Hello,

how can I resolve envionment variables in a string.
e.g.

strVar = /myVar
resolve in
str1 = /mytest02/$MYVAR/mytest02 --> /mytest02//myVar/mytest02
(unix)
str2 =$MYVAR/mytest03 --> /myVar/mytest03 (unix)
str3 =%MYVAR%/mytest03 --> /myVar/mytest03 (windows)
I would not set the variables in this time.

I think I need a little regular expression code snippet, but I have
not work with regular expression before.

Thanks for your help, Kai.
